Ubuntu :: Initramfs On One Of The Kernels?

Aug 28, 2010

I am using Ubuntu 9.10 and am facing an issue while booting up. It goes into initfs command prompt on one of the 4 kernels that show up in the boot menu. I tried to look around for a likely solution and hence did the following:1. ran "chkdsk c: /f" in my windows partition.2. Added "rootdelay=90" in "/boot/grub/menu.lst" file.This is how my /boot/grub/menu.lst file looks and the problem is with the kernel 2.6.31-20-generic:

title Ubuntu 9.10, kernel 2.6.31-20-generic
uuid ceacd229-2b68-41bf-a967-8ee470085fd8
kernel /boot/vmlinuz-2.6.31-20-generic root=UUID=ceacd229-2b68-41bf-a967-8ee470085fd8 ro quiet

After installing Ubuntu 8.4 on an old laptop. Double boot w/ XP. I was brought to the terminal with "initramfs".

Mar 17, 2010

I have one hard drive and one operating system on that one drive. No dual boot, no raid, no windows, no usb boot. Just 9.10 installed on one 40 gb drive. After trying the various techniques from this forum, I'm now stuck at Grub loading, error, grub rescue prompt. No menu list to choose from or edit (e).Here is the output of 'sudo fdisk -l'

Code:

Ubuntu :: Add Curl To Initramfs And A Script Which Uses It

Jun 20, 2010

I am trying to learn how to modify the initramfs in a way which is so Ubuntu-friendly as possible. I do not just want to unpack it, change it and re-pack it, as my changes won't be kept when I upgrade my kernel next time.

What I want to do is: Add curl to the binaries available in the initramfs Add a script which is run after networking is set up which calls curl In case there is no "after networking" I have to setup networking myself using DHCP. There is a tiny client inside BusyBox if I am not mistaken. I have googled a lot to get this information. As well as looked trough more than a few books.

Ubuntu :: Update Initramfs On PXE Server?

Oct 26, 2010

After copying a filesystem to be used as an image on a PXE server, is it possible to update that image's initramfs on the PXE server?

On PXE server, I added several ethernet modules/drivers to the following file:

/nfsroot/etc/initramfs-tools/modules

Before the changes will take effect, I need to run:

Code:

$ sudo update-initramfs -u

Ubuntu :: Update-initramfs From Another Machine?

Jan 24, 2011

I'm finding myself in a situation where I am locked out of my machine (because of a initramfs that doesn't allow me to log in). I think I know where the problem is, but I do not know how to go about rebuilding an initrd file from another machine (especially since my second machine is running on a lower kernel version).

I have tried booting from a LiveCD, but that does not allow me to make any changes to /etc/update-initramfs/. Currently do not have a USB drive handy. How would one go about this?

Ubuntu :: Cannot Delete Partition Due To Initramfs?

Aug 6, 2011

I am having trouble accessing my computer after abruptly shutting it down because it was booting off of a live CD and I just wanted it to boot of the HDD. When I try to boot up from the normal HDD I used to get a lot of errors about /dev/sda being not found, and then it went to an (initramfs) prompt, from which I could do pretty much nothing. I booted into a live CD, and basically I didn't need any of my data so I wanted to just get rid of the problem partition and reinstall. I attempted to delete the partition, but that didn't work, saying something about /dev/sda being busy (even though I had booted from a live CD and had not mounted the partition).

Anyhow, now when I try to boot from the HDD I get:
"Error: no such partition. grub rescue>"

Basically what I'm trying to do is just get rid of this partition and reinstall, but I keep getting errors about it being busy and not being able to delete the partition. Is there someone with a way to allow me to just blast this partition and reinstall? I've got a windows 7 partition on the same HDD and I'd really like to leave that one alone, but the ext4 and swap partition can just go.

Ubuntu :: Clean Up After Update-initramfs -u?

Jun 21, 2010

I'm working on a custom Ubuntu 10.04 live cd, and I've found updating the Plymouth splash uses up a lot more disk space. The culprit seems to be the command update-initramfs -u, which is needed to apply the new splash image. I'm guessing it's making a new intrd image or something.

Ubuntu Installation :: 10.10 Upgrade Won't Boot Initramfs

Dec 13, 2010

I upgrade to 10.10, and now I can't boot normally. The only way I can get X going is if I boot to the previous kernel's recovery mode and choose failsafeX.

In an attempt to fix this, I ran

Code:
dpkg-reconfigure -phigh -a

However, I get this,

Code:

Ubuntu :: Recover From Busybox / Initramfs 8.04 NTFS?

May 22, 2011

I either installed Hardy heron or its predecessor by accident, but began running it exclusively. I did it way back when while trying to create a test drive disk, and I did not repartition the drive, because all my windoze NT stuff survived. I'm now 8.04. Yesterday I had a bunch of updates to do, did them, closed a ton of windows and then pulled up 3 open office files and each, when it came up said there wasn't enough space to save all needed information as they opened. I then closed them and one hung and froze the whole machine, leading me to do a reset. This is BEFORE rebooting from the updates.

Now when I boot into Ubuntu (I'm dual boot) I start to get the opening Ubuntu GUI screen but then get :

BusyBox V1.1.3 (Debian 1.1.1.3-5ubuntu12)built in shell (ash) line followed by:

initramfs)

I'm essentially a total noob, I've rarely used command line and not for a long time. I made a version 11.04 live disk, and it says that the file system is clean, but will not show me any of my old files, only the NT files and directories. I have a ton of unbacked up important data in Hardy Heron so I don't want to do an install from the 11.04 CD.

I've read several threads so far, and can't seem to find anything addressing this that I understand. The drive is a 160GB drive on an HP Pavilion dual core that has a 154GB NTFS boot partition, which is where I'm sure the Hardy Heron files are, and a 6GB FAT32 HP_RECOVERY partition that windoze lists ad drive D (the NTFS is C) The live disk says the FAT32 partition is /dev/sda1 and the NTFS is /dev/sda2

Where should I start? I've seen stuff about booting into recovery mode, but that isn't an option when I boot from the hard drive, and the only older ubuntu disk I have is for 7.something and generates "defective CD" type error messages.

Ubuntu Security :: Prevent Kernel Initramfs Extraction?

Jul 16, 2010

I'm writing here because it's mainly a security issue even though it's rather kernel related.

I'm compiling my own vanilla kernel with an initramfs included in the bzImage. That image contains encryption keys for the rest of the system. Even though it's not for everybody the initramfs image can be extracted from the kernel, decompressed and the keys extracted.
I'm looking on a way to prevent this.

I don't know why this is happened. But before I rebooted, I could not see any content on Windows like update or shut-down (if I tried to install something and it asked for confirmation, that window was blank. Or before I shut down, I had to push enter, since that windows was blank.)

I don't think I installed anything and computer was working just fine before.

Ubuntu :: Unable To Install Initramfs-tools Error In Karmic

Jan 22, 2010

unable to install initramfs-tools error in Karmic I'm having a devilish time installing Karmic on my AMD 64-bit.

Today's missive is:
"Unable to install initramfs-tools."
"Check /var/log/syslog"

After a trying to fix a corrupted 9.04, I have attempted repeated installs of 9.10 on a completely reformatted clean drive. I can get the live CD working, but when I try the permanent install, using the guided full drive install, it stopped at "Unable to install initramfs-tools." and halts the base system install. I can't find anything on this for Karmic and Launchpad says it was superseded.

Can I skip this and go on? It showed a install list going forward, but if I can't put in the base system, how do I proceed? I've burned 2 9.10 disks, a new 9.04 disk, downloaded 9.10 via package manager while in Live CD and get errors on all during the install process. the check sums match on D/L, but I can't figure how to do a chksum after it's burned to disk. The file sizes do match, but when I go for the install something always halts it at different steps with different errors. No joy.

Ubuntu Installation :: Server Won't Start Properly - Goes To Initramfs Prompt

May 31, 2010

I'm trying to install ubuntu-10.04-server-i386 in Virtualbox on Windows XP Home (for use as a Drupal development server) using the instructions here [URL]... the Ubuntu server will not start properly. Instead it goes to an initramfs prompt as follows

[code]...

Another thread suggested typing 'exit' after a while but it just repeats the same output. It seems the root disk doesn't exist. I allowed the installer to set up partitions to its own recommendation (Guided?) although I'm not entirely sure what it did - I think there are two partitions but you guys will know that. The host disk is SATA. The CPU is a dualcore but I've only enabled one CPU on the guest within Virtualbox. Also, I had to enable PAE mode as without it Virtualbox crashed every time I started the guest. PAE wasn't mentioned in the instructions mentioned above. I've tried changing the various other disk parameters in Virtualbox (without fully understanding them) but no luck. I also ran run the boot info script from a desktop LiveCD and the results are given below.

Ubuntu Installation :: Booting From Live CD Fails - Initramfs Error

Jan 22, 2011

Put together a PC using the following:

Foxconn M61PMP-K AM3 NVIDIA MCP61P Micro ATX AMD Motherboard
AMD Athlon II X2 240 Regor 2.8GHz Socket AM3 65W Dual-Core Processor ADX240OCGQBOX
Patriot 2GB 240-Pin DDR3 SDRAM DDR3 1333 (PC3 10600) Desktop Memory Model PSD32G13332
HITACHI Deskstar 7K1000.C HDS721010CLA332 (0F10383) 1TB 7200 RPM SATA 3.0Gb/s 3.5" Internal Hard Drive -Bare Drive

Plus an old case and PSU and an old 18gb IDE drive, and an old CD-RW drive

I put the CD in and boot the machine. The initial Ubuntu screen comes up ("Ubuntu" with the line of dots below it) for a few seconds, and then it disappears and I see this text:

(initramfs) mount: mounting /dev/loop0 on //filesystem.squashfs failed: Input/output error
Can not mount /dev/loop0 (/cdrom/casper/filesystem.squashfs) on //filesystem.squashfs

At that point it hangs and will proceed no further. I've tried this with the latest Mythbuntu Live CD and the latest Ubuntu Desktop Edition Live CD. Both were x64 versions.

Ubuntu :: Hardy Boot Failed After Update Drop To Initramfs

Apr 5, 2011

just installed hardy after I removed Maverick since it doesn't support my ati graphics. I installed it inside my windows xp pro and run smoothly after installation, added couple of widgets and so on... after I restarted it the next time, a balloon showed on top saying 113 or so updates are available, so I updated it.

After update I reboot my lappy and it won't get to my ubuntu anymore but works fine with my xp. I tried several searches on the net to find the solution but can't really figure it out. I just tried running Boot info script as it might help experts figure out what's wrong with my box and here's what it shows:

General :: Busybox/Initramfs Prevents Launch Of Ubuntu Server 8.04.3?

Sep 27, 2009

Prior to posting this I entered search arguments, "Busybox," then "initramfs" to attempt to find another user who may have experienced the same thing; if the solution is imbedded in the message threads, I must have missed it. On hand is a Ubuntu Server 8.04.3 installer CD. What works: Installs to a Mac Pro under both Parallels, and then under Fusion both were successful first try.

Install to a newly purchased 2 gig Acer Aspire One seems to have succeeded, but upon launching from Grub, Busybox/initramfs intercepts and halts the launch with an error I don't understand:

Starting up ...
Loading, please wait ...
Check root = bootary cat /proc/cmdline

[code]....

The new Acer-PC Aspire One was partitioned into four 80 gig partitions using the Paragon software to do the partitioning. XP is on the first, and Ubuntu Server on the next 80 gig partition. Install was "successfully" done from a Lite-On external CD/DVD over USB.

During the install I changed the default name from Ubuntu to something else (probably a bad idea), and I naively entered "/" root to answer the mount question (finding nothing to tell me what to do). Ubuntu required a disk driver choice from a long list - finding no reference or guidance as to what to enter, I naively entered IDE Generic, and it took (I guess it "took").

FWIW the Ubuntu installer didn't require me to indentify the mount entry or the disk driver during installs on my Mac (Fusion/Parallels).I did connect the Internet during the install. I did checkoff/install LAMP during the install from CD. Goal: To use Joomla in a mock server environment.
